What are the classifications of geotextiles? Tai'an Tenglu Engineering Materials Co., Ltd. will answer your questions

Geotextile has the functions of filtration, drainage, isolation, reinforcement and protection, and has the characteristics of light weight, high tensile strength, good permeability, high temperature resistance, freezing resistance, aging resistance and corrosion resistance. The application of geosynthetics originated in the 1950s. The domestic geotextile is one of the eighth five-year plan of the country. At present, the geotextile has been widely used in many fields.

Geotextiles mainly have the following three series:

1. Needle-punched non-woven geotextile, the specifications are arbitrarily selected between 100g/m2-600g/m2, the main raw material is polyester staple fiber or polypropylene staple fiber, made by acupuncture method, the main uses are: river, sea, lake and river Slope protection of embankments, land reclamation, docks, ship locks, flood control and emergency rescue projects are effective ways to conserve soil and water and prevent piping through backfiltration.

2. Acupuncture non-woven fabric and PE film composite geotextile, the specifications are one fabric and one film, two fabrics and one film, and the width is 4.2 meters. The main raw material is polyester staple fiber needle-punched non-woven fabric. The main purpose is anti-seepage, suitable for railways, highways, tunnels, subways, airports and other projects.

3. Non-woven and woven composite geotextiles, varieties of non-woven and polypropylene filament woven composite, non-woven and plastic woven composite, suitable for basic engineering facilities for foundation reinforcement and adjustment of permeability coefficient.

Features:

Light weight, low cost, corrosion resistance, excellent performance such as anti-filtration, drainage, isolation and reinforcement.

use:

Widely used in water conservancy, electric power, mine, highway and railway and other geotechnical engineering:

l. Filter material for soil layer separation;

2. Drainage materials for mineral processing in reservoirs and mines, and drainage materials for high-rise building foundations;

3. Anti-scour materials for river dams and slope protection;

4. Reinforcing materials for railways, highways, and airport runways, and for road construction in swampy areas;

5. Anti-frost and anti-freeze thermal insulation materials;

6. Anti-cracking material for asphalt pavement. The staple fiber acupuncture geotextile is made of short fiber as raw material and is processed by carding and laying equipment and acupuncture equipment.

Features: The product has excellent properties such as acid and alkali resistance, corrosion resistance, aging resistance, high strength, dimensional stability, and good filterability.

Uses: Mainly used for engineering enhancement, isolation, reverse filtration, drainage, widely used in water conservancy, highway, railway and other fields.
